Hey. Firstly does the 'top spec calmer' seem to be effective? Or has he become immune to it at all? Might be worth trying to change it or use a long term relase such as B+ (I think, can't remember off hand, came from holland and barret)
What type of lead is his show lead? I have found dogs respond different to different leads, some checks, some half checks, slip lead etc etc etc might be worth tryiing a different one?
Is he interested in the bait? Can it get his attention AND keep it?
Although she has phsical control over him does she have verbal control? will he listen to her? I can physically control my setters (wouldn't handle them if I could!) but I can also verbally control them. There's a difference between stopping a dog doing something with voice and signals compared to picking them up and removing them :) (although must admit can't pick a setter up easily!!!!!!)
If he is slightly better with you I would say he respects you more. Any dog if they feel can get away with something then they will :)
Whats he like on his walks aswell? is he just as excitable seeing other dogs then?
Without seeing the dog and handler interaction it's hard to really say how to go about it however I think the first step you need to take it calming him down. Take him to the training classes but don't work him. Sit down and watch, make him stay calm. Lots of praise when calm and behaving, being corrected and calmed down when not. If you can use the treats to get his attention back onto you (or your daughter, whoever is taking him) and praise him. It might also be worth getting him to obedience classes if possible to try and get him into control. If your daughter does this it will also help her gain confidence with him and will make him realise she is there to praise and reward him for behaving :)
Ok I shall leave the post at that for now before I confuse myself, let alone you! :D
Ok one more thing...I would leave the table work out of the equation for a while and keep him on the floor untill he calms down abit. Before he does any damage to himself more then anything.
